You will “keep” the most color after drying/curing by choosing strains that are dark purple through and through, from buds to pistils to leaves if at all possible. Deeply colored buds keep more of their color after drying and curing than pale purple or pink buds.
Buds may still be purple-tinted from leaves that weren’t completely trimmed off.
Cannabis sometimes has neat mutations, like this two-tone plant where only half the leaves turned purple!
- Pistils (Hairs) – some of the color remains after drying/curing
- Calyxes (Buds Themselves) – very strong effect on final color
- Leaves – relatively small effect on final bud color since many are removed by trimming
- Trichomes – small effect on final color
Certain strains like Querkle turn color more easily when the temperature is warm during the day as opposed to cool at night. So, it’s always a good idea to aim for nice warm days, and cool, comfortable nights, because that contrast seems to help bring out colors for many strains.
There are two parts of the buds that can turn color. One part is the pistils/hairs that stick out. There are several strains where the pistils turn pink or purple.
With some cannabis strains, the leaves may turn purple while the buds stay green. Just like with buds, the leaves are more likely to turn color when the plants are getting cool night temperatures in the late flowering stage.
- Warm Days (75-80°F / 24-27°C)
- Cool Comfortable Nights (65-70°F / 18-21°C)
This Purple Trainwreck bud turned particularly purple.
